Defining and Calling Methods

Methods are reusable blocks of code. 'void' means the method does not return a value, and parameters allow you to pass data into the method.

java
public static void greet(String user) {
    System.out.println("Hello, " + user);
}
 
// Calling the method
greet("Alice");
